Figure 3 is a detail sectional `view` illustrating the means for adjusting the water wheel vertical.- 1y within the fiume. i

` `Figure 4 `is a side elevation., partly in section,

Figure 5 is a transverse sectional View illustrat- 3` ing a, cylinder acting as a fish stop.

Figurel 6 is a perspective view illustrating one ofthe rodsiand its fingers forming a part of the p cylinder. i i f f p p Referring in detail to therdr'awings, the character `A indicates a main body of water and B l indicatesan irrigation 'ditch connected With said body of `y'va'ter.` To prevent iish from passing jfrom the mainbodyof water into the irrigation dltchthe present invention is employed and con- `sists primarily of a flume 'located in the ditch where the latter` joins onto` the main body of water.` The `flume includes a bottom wallIi and* side walls 1. The bottom wall` rests on the bottom"of` the ditch and the side walls snugly fit the sides of the ditch so thatnthe water of the ditch must floWen-tirely through the flume. The

side walls are connected by tie rods 8 adjacent the ends of the ume y thereof `which isthelfelosestto the main body o! 'water is a rotatable cylindrical ishstop 9. 'The stop 9 extends transversely of the flume and in cruces a shaft lo journaied in the side wanaA end i discs I-I-secured on` saidshaft and located in cioselproximity to the side Walls Iliiof the flume fandconnected4 bytierodsf I 2 located adjacent the peripheriesof" the discsfII and on which are tie `nods and discs'support foramin'ous materia] "Il" through which "the "fin-gers I3 project.

Thus it `willoe'seerltlixa.t-l;lie stop k9 is in the form of a" fcraminoiis'cylinder which will permitnowof water therethrough and through the nume, smi

l villpreventlflsh `from passing vthrough theuxe due toits construction and location inthe flume.

v"wheneverfthe're is alow of `water throughfthe nume 'audio accomplishment water wheel is isqprovided forfthe drive or rotation ofthe mh TOnelof wthe side walls il ofthe` nume 5 is odset to form; a poclget y-liin which approximately one-V hallfoi vaterwiieelds'located while the other haii `ofthei"*wa/'tiert"wheel operatesin the flow of `waterinfringirmenoline. The water in thepock; et, naturally/*will havevery much less flow than the water passing directly throughthe flume and l as the non-driving portion of the Water Wheelis' located in` said pocket thewater retard to the drive of the Wheel will be materially reduced. This arrangement will permit the water wheel to develop greater power.

A shaft I8 is journaled vertically in the `iiume Y downstream from the fish stopby having its` 10Weend supported by a bearing I9 carried by theV bottom wall of the flume. The shaft I8 is furthery rotatably supported by a member 20 `ar f ranged transversely of the ume and supported `by the side Walls thereof. The upper end of the `shaft I8 lsigeared to a horizontalshaft 2| journaled'in bearings 22 on the supporting member 20 and extendsthrough `the side wallsandhas one end connected to the shaft I0 of the fish l 'stop 9by `sprocket lgears 23 and an endless i sprocket chain 24.

A hun 25 including a disc z'sris -spiined for vertical movement onr the shaft I8 and a supporting member 21 is secured on the shaft I8 above the disc26 and includes hollow depending arms 28 to whichare'threaded bolts 29. The bolts 29 are carried `by the `disc 26 and by adjusting the bolts in the arms "28tlie disc 2liI can beadjusted vertically on `the shaft I8 in either direction.

Rods 30 are secured on the disc 26'and extend radially therefrom and have journaled thereon paddles 3l. Suitable means 32 are provided for limiting the journaling of the paddles 3| on the rods 30. The purpose of the limiting means 32 for the paddles 3l is to maintain said paddles in a depending position when acted upon bythe flow of wate'rthrough the flume.' However, when the paddles movev into the pocket I6 they may be feathered due to the limiting means permitting said paddles to be swung upwardly to present edges thereof to the water as the wheel',

rotates.

A cam 33 is located in the *pocket I6' of the' v flume, the purpose of which'is to bring about feathering of the paddles during their movement through the pocket and permitting said paddles as they move out of the pocket to assume depending position in order that they may be acted upon by the iiow of water through the flume. By'

Guard membersof arcuate formation, as ini dicated at 34, are mounted in the fiume upstream from the stop. The guard membersare located adjacent the side-walls of thel iiume to prevent foreign matter from entering the spaces between jumping over the stop owing to the panel ork plate gravitating into a oating position, as shown in Figure 2, as soon as freed of debris.

-1 l, vWhile the preferred embodiment ofthe invention has been shown and described, it will be understoo-d that minor changes in construction,

' combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described the invention, what is claimed is:

In ar device of the class described, a fiume for conveying water and having a -sidepocket therein for retardingthe passage of water therethrough, a iiow operative water power wheel in said flume comprising a shaft journaled inY the fiume in upright position, a hub forming disk splined on said shaft for vertical adjustment thereon, rods fixed at inner ends thereof on said disk to extend radially therefrom, normally pendent blades vertically-swingable on said rods to feather the Same and having outer ends rotatableintorand out of said pocket to provide fork low resistance to rotation of said wheel onv onei side thereof,

the ends of the iish stop and the side wallsof theiiume f A fish check panel of buoyant .material is hingedon the tie rod 8 of the flume located upstream from the stop 9. The check panel 35 mounted as described and being buoyantwill swing in the direction of the stop 9 by the ow of water through the flume from the main body of water Aso asto prevent fish from jumping overthe stop. Sufficient space is provided 1between the free edge of the check plate or4 panel 35 and the periphery of the' stop 9 or the free vmeans to adjust said hub vertically into different set 'positions tor correspondingly adjust said blades in accordance with. variations in the level ofthe water in said flumecomprising a hub supporting member fast on'said shaft above the huband provided with hollow arms depending therefrom,j and headed adjusting'rcds extending upwardly' through 7said disk and threaded into said arms, and vmeans' in said,pocket to` cause swinging c-f said blades as said outer ends ofr the blades,` rotate through the pocket. i i y l f FLOYD L.
